That's a very thoughtful gift though it might end up being less useful than intended, especially for the cost. I ran through Amazon and snagged some stuff that I think might be good substitutions. I know gift ideas can be difficult so I listed out a bunch of stuff I personally use, even if the total price exceeded the item that you had originally mentioned.
(Insaniac's suggestion of a portable lamp is excellent, though I don't have any suggestions for the price, make, and model.)
